WhatFirst, check with your WWAN ISP and ask if they support voice calls over their network and have an app for that. If not, you need is a Voice Over IP client app (AKA 'softphone') for Debian, such as one of these listed at https://www.linuxlinks.com/voip/ and https://www.ubuntupit.com/top-20-best-linux-voip-and-video-chat-software/ (there are many more).

I've used T-Mobile, ATT, and Sprint voice clients from Windows laptops with WWAN cards, but none of them supported Debian.

You may also need an account with a telephone providerprovider; maybe your ISP provides this, maybe they don't. Depending on where you are, Google Voice may be free (US & Canada, IIRC) if you have a Gmail or other Google account, and works well if you launch it from within Chromium or Chrome.

Skype allows outbound calls for free the last time I looked, but getting a PSTN ('Public Switched Telephone Network') number was not free, so you would be limited to other Skype users unless you paid.

The last time I had a paid account for PSTN access not with Google or Skype, I paid by the minute plus per call connection plus a flat monthly fee, but it wwas very reasonable.

Your WWAN provider also may block softphone calls; it's up to their Terms and Conditions.
